There is going to be a new forum created just for the Kademlia side of the client.. If you feel there is an error or a way to improve something, please post it in the forum first and let us look at it.. If it is a real improvement, it will be added to the offical client.. Changing something without knowing what all it does can cause great harm to the network if released in mass form.. Any mod that changes anything within the Kademlia side will not be allowed to advertise there client on the eMule forum.. */ #include "stdafx.h" #include "LittleEndian.h" #ifdef _DEBUG #undef THIS_FILE static char THIS_FILE[]=__FILE__; #define new DEBUG_NEW #endif //////////////////////////////////////// namespace Kademlia { //////////////////////////////////////// //NOTE: avoid those function whenever possible -> terribly slow uint16 le(uint16 val) { uint32 b0 = (val ) & 0xFF; uint32 b1 = (val >> 8) & 0xFF; return (uint16) ((b0 << 8) | b1); } //NOTE: avoid those function whenever possible -> terribly slow uint32 le(uint32 val) { uint32 b0 = (val ) & 0xFF; uint32 b1 = (val >> 8) & 0xFF; uint32 b2 = (val >> 16) & 0xFF; uint32 b3 = (val >> 24) & 0xFF; return (b0 << 24) | (b1 << 16) | (b2 << 8) | b3; } //NOTE: avoid those function whenever possible -> terribly slow uint64 le(uint64 val) { uint32 b0 = (val ) & 0xFF; uint32 b1 = (val >> 8) & 0xFF; uint32 b2 = (val >> 16) & 0xFF; uint32 b3 = (val >> 24) & 0xFF; uint32 b4 = (val >> 32) & 0xFF; uint32 b5 = (val >> 40) & 0xFF; uint32 b6 = (val >> 48) & 0xFF; uint32 b7 = (val >> 56) & 0xFF; return ((uint64)b0 << 56) | ((uint64)b1 << 48) | ((uint64)b2 << 40) | ((uint64)b3 << 32) | ((uint64)b4 << 24) | ((uint64)b5 << 16) | ((uint64)b6 << 8) | (uint64)b7; } } // End namespace
